Title: Preventing wear in centrifugal pumps
Inventor: BARKER MICHAEL D
IPC: F04D29/42
Filed: 1982-07-23
Abstract: The pump impeller 12 includes a rear plate 16 and a plurality of curved blades 18 radiating from an open central portion 20 of the rear plate 16. An annular plate 24 is fixed to the outermost edges of the blades 18 at the inlet side of the impeller 12. A cylindrical sleeve 26 extends in an axial direction from near the inner edge of the annular plate 24 through the opening 36 in a wear plate 34. The annular plate 24 and sleeve 26 protect the edge of the wear plate 34 around the opening 36 and prevent damage to the wear plate 34 when the pump 10 is used to pump slurry containing grit or sand. A shroud 38 is mounted on the wear plate 34 and extends around the free end of the sleeve 26 to prevent grit entering between the outside of the sleeve 26 and the wear plate 34 and flowing between the annular plate 24 and the wear plate 34. <IMAGE>
Patent GB-2117400-A (GB)
Title: Catalytic metal
Inventor: BALDI ALFONSO LOUIS
IPC: C23C22/74
Filed: 1982-09-13
Abstract: Platinum wire activated by aluminium diffusion and leaching and containing from 0.5 to 5% aluminium with optionally up to 15% of another Pt group metal in the outermost 0.3 mil (7.62  mu m) is heated to a temperature of from 1800 to 2300 DEG F (962-1260 DEG C) for at least one week, whereby the useful life of the platinum wire is increased. The increase of useful life results from the fissures in the wire surface becoming less pronounced. A catalytic pyrophoric composition is obtained when a metal substrate, e.g. Ni, Fe, Ti, PT or Pd, is heated with Al, Zn or Sn to diffuse it into the substrate and then at least part of the diffused metal is leached out with NaOH or HCl. The pyrophoric nature of the composition is enhanced by dipping in a solution of selected oxidising agents and drying in an inert gas. The composition is stored in an inert liquid or gas. If the liquid is vaporisable, the pyrophoric properties re-emerge on drying in air. Flares are made by associating the composition with ignitable material and may be prepared in and dispersed from suitable packings. The pyrophoric properties are eliminated by treatment with hydrogen peroxide, the catalytic properties remain.

Patent GB-2112575-A (GB)
Title: Electrical pushbutton switch
Inventor: MINKS WERNER
IPC: H01H13/02
Filed: 1982-12-07
Abstract: A pushbutton switch for use with keyboards or keypads, has a cover plate (4) and an internal contact- carrying plate (2) which have associated openings for key plungers (6). A collar (10) is provided around each opening of the contact- carrying plate (2) which, in every position of the associated key plunger, is surrounded by a sleeve- shaped member (11) of the key plunger. The relatively close fit of the collar and the sleeve-shaped member provides a substantially dust-tight enclosure. The lengths of both the collar and the sleeve- shaped member are such that contacts (18, 19) can be actuated with subsequent over-travel of the plunger (6), thereby ensuring that depositions on the plate (2) do not impede actuation of the contacts (18, 19). <IMAGE>

Title: Machine for washing articles such as kegs
Inventor: LAMBRECHTS JULIAAN MARCEL
IPC: B08B9/08
Filed: 1983-01-17
Abstract: A machine for washing cylindrical articles such as kegs comprises a tunnel provided with spray means 26, 44, 46 to spray cleaning liquid onto the kegs as they are carried on a conveyor 14 through the tunnel. The spray means includes at least one spray head 40 arranged to direct a fine jet or jets of liquid at high pressure onto an end face of each keg and to move the jet or jets over substantially the whole of the end face. The fine jets cut through any labels on the end face, to allow the cleaning liquid to get to the adhesive by which the labels are fixed. The labels are therefore removed completely by the high pressure jets, or by the subsequent action of low pressure jets 26 in the tunnel. This obviates the need for brushes to brush the kegs mechanically as they pass through the tunnel. The spray head includes an arm 42, rotatable about a vertical axis and axially adjustable to accommodate different size kegs, and nozzles 44, 46 on the arm are spaced at different distances from the axis. <IMAGE>
Patent GB-2122799-A (GB)
Title: Improvements in or relating to video tape players and pre-recorded cassettes therefor
Inventor: SCARGILL PETER DONALD
IPC: G11B15/00
Filed: 1983-03-07
Abstract: A coin operated video tape player or video juke box retrieves and plays on a monitor information streams recorded in a video track and a first audio track at spaced locations along the tape. A control unit memorises the start and stop position of each selection along the tape. In fast forward or rewind to the start of a selected information stream the control unit uses control track pulses to monitor tape movement but when in normal play it receives and decodes frequency shift keyed tones recorded in a second audio track and defining digitally encoded incrementally numbered positions along the tape. When the required selection has been reached, the input to the monitor is switched from a continuously available source such as graphics recorded in a read-only memory to the output from the tape player. Wallboxes connected in a ring to the control unit provide for remote selection entry and the machine may be arranged to play certain selections under the command of a programable timer controlled by a real-time clock. Simultaneous operation of two tape players is also possible with one player in normal play where the other player is accessing the required selection.

Title: Improvements in vortex flowmeters
Inventor: GRALEWSKI ALEKSANDER ZDZISLAW
IPC: G01F1/32
Filed: 1983-08-18
Abstract: A flowmeter has a bluff body (7) which causes vortices to be generated. A sensing body (3) extends into the fluid, and is caused to bend by the vortices. An indicating element (11), not contacted by the fluid, extends from a predetermined location on the sensing body. This location may be within the fluid, in a hollow end section (9) of the sensing body, or it may be at the supported end of the body. The dimensions of the sensing body (3) and the indicating element (11) are such that the element is not deflected when the support for the sensing body is subjected to forces which cause accelerative movement thereof caused by external vibration for example. When the sensing body is caused to bend by the vortices, however, the indicating element (11) moves in a manner which represents the movement of the predetermined location on the sensing body. The indicating element (11) may include optical means (6, 12) or piezoelectric means. <IMAGE>
